PvE Mount - Fire "Raven God" / Flametalon of Alysrazor
The Fire "Raven God" model is the Flametalon mount from Flametalon of Alysrazor. The mount isn't listed as a loot from Alysrazor in the Encounter Journal for the moment but it's very likely that it will drop from this boss, let's just wait and see if there's an official confirmation in an upcoming PTR build.
